tbc,
Why does the rotating cone rotate fully open right? Except for autorotation, rapid decelerations and maybe VSCS hardover (never heard of one happening) your thruster doesn't go much more right than neutral. I could see getting stuck right in an aggressive decel and banging the tail on the ground.
The first thing I would do is put my pedals to a minimum fan pitch setting, approximately 1 inch right pedal forward. This will minimize the effect of the thruster, relative to the opening position. It will also give airflow to operate the slots which will help develop the COANDA effect, once / if you get the forward speed minimized depending on your approach technique.
Remember- if the thruster is open to the right, left or right pedal application will give you increased nose right yaw.
Following the flight manual emergency procedure loss of thrust or fixed thruster neutral to right will give you an option of landing with near zero groundspeed. This may take a couple approaches depending on conditions, but the NOTAR system / VSCS system does give you some good leeway to practice before you commit to a landing. You may try with SAS on, SAS off and also VSCS off- all will have an effect on the outcome of the maneuver depending on the conditions. Remember- if you turn the VSCS off and then find you need to do a go-around- you have to get them turned back on as you increase power. Also do not turn them off until you have started your descent on your approach angle.
You an talk all day about this, but knowing the systems that effect anti-tq will help you understand this. If you haven't been taught the techniques for aggressive deceleration (getting the machine to a hard, smooth landing area with minimum forward speed) and then getting the machine on the ground from a low hover, with a yaw rate building- I would recommend going to the factory and seeing it and practicing in their aircraft.
